Sols 4300-4301: Rippled Pages NASA’s Mars rover Curiosity prepares for a thorough examination of the unusual, dark “Tungsten Hills” rocks in front of it, studying these rugged boulders covered in paper-thin sedimentary layers, some of which contain intriguing ripple structures that may have formed in running water or windblown sand. This image was taken by Left Navigation Camera aboard Curiosity on Sol 4298 — Martian day 4,298 of the Mars Science Laboratory mission — on Sept. 8, 2024, at 06:35:57 UTC.NASA/JPL-CaltechEarth planning date: Monday, Sept. 9, 2024
With today’s plan, Curiosity completes its most southerly planned exploration of the Gediz Vallis channel. From here, our rover will head north and climb out of the channel to explore terrain to the west. Our planned drive to the “Tungsten Hills” rocks, named for a famous mining district near Bishop, California, completed successfully over the weekend, placing a pile of unusual dark rocks within our workspace. Curiosity is currently in the “Bishop” quadrangle on our map, so all targets in this area of Mount Sharp are named after places in the Sierra Nevada and Owens Valley of California. On sols 4300-4301, Curiosity will perform a thorough examination of these rugged boulders, which are covered in paper-thin sedimentary layers like the pages of a book (see image). Some layers have intriguing ripple structures that may have formed in running water or windblown sand. These features are the prime targets for contact science and remote observation at this location.
On Sol 4300, Curiosity will obtain ChemCam laser spectra and Mastcam imagery on a part of the closest plate-like rock called “Bonita Flat,” after a high valley above the southern Kern River canyon in Sequoia National Forest. ChemCam will also obtain telescopic views of a section of the Gediz Vallis channel banks with its RMI camera. Mastcam will take a mosaic of the upper reaches of the channel, then turn its cameras on the interesting bedrock of “Coffeepot Canyon,” honoring a ravine along the precipitous East Fork of the Kaweah River canyon in Sequoia National Park, unfortunately now engulfed in a huge wildfire.
The first science block ends with atmospheric observations, including a dust-devil movie, supra-horizon cloud imaging, and Mastcam measurement of dust in the air across the crater. Curiosity will then use its arm to brush the dust from the closest block in an area dubbed “Pond Lily Lake,” for a petite meadow lake atop the canyon wall of the San Joaquin River, downstream of Devil’s Postpile National Monument. This cleared spot will then be imaged by MAHLI and Mastcam, and its composition will be measured by APXS spectroscopy. MAHLI will perform an intricate “dog’s eye” maneuver to obtain detailed images of ripples in “Window Cliffs,” named after sheer walls above the spectacular fault-controlled Kern River canyon west of 14,505-foot Mount Whitney, the tallest peak in the lower 48 states. MAHLI wraps up a very full day of work by imaging the scalloped edge of the largest nearby block, dubbed “Boneyard Meadow” for a wetland in the western Sierra foothills where many sheep sadly perished due to a late spring snowstorm in 1877.
Early on sol 4301, Curiosity will use Mastcam to thoroughly document the Tungsten Hills in pre-sunrise morning light. Later in the day, a second science block starts with ChemCam spectroscopy and Mastcam imagery of “Castle Domes,” honoring the granite domes of Castle Valley, acclaimed as some of the most beautiful mountain scenery in Kings Canyon National Park. ChemCam RMI will perform telescopic observations of the channel floor. Mastcam will look for possible sulfur rocks at the base of the Tungsten Hills blocks in a target named “Hummingbird Lake,” for an alpine lake at 10,000 feet between Bloody and Lundy Canyons near Mono Lake. This science block of the plan ends with Navcam deck monitoring, dust measurement, and a large dust-devil survey. Curiosity will then drive north, taking a MARDI “sidewalk” video of the terrain under the rover during the drive.

30 Years Ago: STS-64 Astronauts Test a Spacewalk Rescue Aid
On Sept. 9, 1994, space shuttle Discovery took to the skies on its 19th trip into space. During their 11-day mission, the STS-64 crew of Commander Richard “Dick” N. Richards, Pilot L. Blaine Hammond, and Mission Specialists Jerry M. Linenger, Susan J. Helms, Carl J. Meade, and Mark C. Lee demonstrated many of the space shuttle’s capabilities. They used a laser instrument to observe the Earth’s atmosphere, deployed and retrieved a science satellite, and used the shuttle’s robotic arm for a variety of tasks, including studying the orbiter itself. During a spacewalk, Lee and Meade tested a new device to rescue astronauts who found themselves detached from the vehicle. Astronauts today use the device routinely for spacewalks from the International Space Station.

In November 1993, NASA announced the five-person all-veteran STS-64 crew. Richards, selected as an astronaut in 1980, had made three previous spaceflights, STS-28, STS-41, and STS-50. Lee, a member of the astronaut class of 1984, had two flights to his credit, STS-30 and STS-47, as did Meade, selected in 1985 and a veteran of STS-38 and STS-50. Each making their second trip into space, Hammond, selected in 1984 had flown on STS-39, and Helms, from the class of 1990 had flown on STS-54. In February 1994, NASA added first time space flyer Linenger to the crew, partly to make him eligible for a flight to Mir. He holds the distinction as the first member of his astronaut class of 1992 to fly in space.

Discovery returned to NASA’s Kennedy Space Center (KSC) in Florida following its previous flight, the STS-60 mission, in February 1994. Workers in KSC’s Orbiter Processing Facility (OPF) removed the previous payload and began to service the orbiter. On May 26, workers moved Discovery into the Vehicle Assembly Building for temporary storage to make room in the OPF for Atlantis, just returned from Palmdale, California, where it underwent modifications to enable extended duration flights and dockings with space stations. Discovery returned to the OPF for payload installation in July, and rolled back to the VAB on Aug. 11 for mating with its external tank and solid rocket boosters. Discovery rolled out to Launch Pad 39B on Aug. 19, with its sister ship Endeavour still on Launch Pad 39A following the previous day’s launch abort. The six-person crew traveled to KSC to participate in the Terminal Countdown Demonstration Test, essentially a dress rehearsal for the launch countdown, on Aug. 24.
Liftoff of Discovery on the STS-64 mission.
On Sept. 9, 1994, after a more than two-hour delay caused by inclement weather, Discovery thundered into the sky to begin the STS-64 mission. Eight and a half minutes later, the orbiter and its crew reached space, and with a firing of the shuttle’s Orbiter Maneuvering System (OMS) engines they entered a 160-mile orbit inclined 57 degrees to the equator, ideal for Earth and atmospheric observations. The crew opened the payload bay doors, deploying the shuttle’s radiators, and removed their bulky launch and entry suits, stowing them for the remainder of the flight. They began to convert their vehicle into a science platform.

One of the primary payloads on STS-64, the LIDAR (light detection and ranging) In-space Technology Experiment (LITE), mounted in Discovery’s forward payload bay, made the first use of a laser to study Earth’s atmosphere, cloud cover, and airborne dust from space. Lee, with help from Richards and Meade, activated LITE, built at NASA’s Langley Research Center in Hampton, Virginia, on the flight’s first day. The experiment operated for 53 hours during the mission, gathering 43 hours of high-rate data shared with 65 groups in 20 countries.

The Shuttle Plume Impingement Flight Experiment (SPIFEX), built at NASA’s Johnson Space Center (JSC) in Houston, consisted of a package of instruments positioned on the end of a 33-foot boom, to characterize the behavior of the shuttle’s Reaction Control System (RCS) thrusters. On the flight’s second day, Helms used the shuttle’s Remote Manipulator System (RMS), or robotic arm, to pick up SPIFEX. Over the course of the mission, she, Lee, and Hammond took turns operating the arm to obtain 100 test points during various thruster firings. A video camera on SPIFEX returned images of Discovery from several unusual angles.

Middle: Discovery approaches SPARTAN during the rendezvous. Right: Astronaut Susan J. Helms operating the Shuttle’s Remote Manipulator System prepares to grapple SPARTAN.
On the mission’s fifth day, Helms used the RMS to lift the Shuttle Pointed Autonomous Research Tool for Astronomy-201 (SPARTAN-201) satellite out of the payload bay and released it. Two and a half minutes later, SPARTAN activated itself, and Richards maneuvered Discovery away from the satellite so it could begin its science mission. On flight day seven, Discovery began its rendezvous with SPARTAN, and Hammond flew the shuttle close enough for Helms to grapple it with the arm and place it back in the payload bay. During its two-day free flight, SPARTAN’s two telescopes studied the acceleration and velocity of the solar wind and measured aspects of the Sun’s corona or outer atmosphere.

On flight day seven, in preparation for the following day’s spacewalk, the astronauts lowered the pressure in the shuttle from 14.7 pounds per square inch (psi) to 10.2 psi to reduce the likelihood of the spacewalkers, Lee and Meade, from developing decompression sickness, also known as the bends. As an added measure, the two spent 15 minutes breathing pure oxygen before donning their spacesuits and exiting the shuttle’s airlock.

Meade tests the SAFER during an untethered spacewalk. Right: Meade, left, tests the ability of the SAFER to stop his spinning as Lee looks on.
The main tasks of the spacewalk involved testing the Simplified Aid for EVA (Extravehicular Activity) Rescue (SAFER), a device designed at JSC that attaches to the spacesuit’s Portable Life Support System backpack. The SAFER contains nitrogen jets that an astronaut can use, should he or she become untethered, to fly back to the vehicle, either the space shuttle or the space station. The two put the SAFER through a series of tests, including a familiarization, a system engineering evaluation, a crew rescue evaluation, and a precision flight evaluation. During the tests, Lee and Meade remained untethered from the shuttle, the first untethered spacewalk since STS-51A in November 1984. Lee and Meade successfully completed all the tests and gave the SAFER high marks. Astronauts conducting spacewalks from the space station use the SAFER as a standard safety device. Following the 6-hour 51-minute spacewalk, the astronauts raised the shuttle’s atmosphere back to 14.7 psi.

Mission managers had extended the original flight duration by one day for additional data collection for the various payloads. On the planned reentry day, Sept. 19, bad weather at KSC forced the crew to spend an additional day in space. The next day, continuing inclement weather caused them to wave off the first two landing attempts at KSC and diverted to Edwards Air Force Base (AFB) in California.

On Sept. 20, they closed Discovery’s payload bay doors, donned their launch and entry suits, and strapped themselves into their seats for entry and landing. They fired Discover’s OMS engines to drop them out of orbit. Richards piloted Discovery to a smooth landing at Edwards, ending the 10-day 22-hour 50-minute flight. The crew had orbited the Earth 176 times. Workers at Edwards safed the vehicle and placed it atop a Shuttle Carrier Aircraft for the ferry flight back to KSC. The duo left Edwards on Sept. 26, and after an overnight stop at Kelly AFB in San Antonio, arrived at KSC the next day. Workers there began preparing Discovery for its next flight, the STS-63 Mir rendezvous mission, in February 1995.

Almost a decade ago, then-grad student Kyle Helson contributed to early paperwork for NASA’s EXCITE mission. As a scientist at Goddard, Helson helped make this balloon-based telescope a reality: EXCITE launched successfully on Aug. 31.
Name: Kyle Helson
Title: Assistant Research Scientist
Organization: Observational Cosmology Lab (Code 665), via UMBC and the GESTAR II cooperative agreement with NASA Goddard
How did you know you wanted to work at NASA Goddard?
When I was finishing my physics Ph.D. at Brown University in 2016, I was talking to Ed Wollack and Dave Chuss at Goddard about the NASA postdoc program, and they suggested I apply. Luckily, I got the postdoc fellowship to come here to Goddard to work on cosmic microwave background detector testing and other related research.
I don’t think I would have realized or been interested in coming here had I not had that NASA Space Technology Research Fellowship when I was in grad school and gotten the opportunity to spend some time here and work with Ed and Dave.
What is the name of your team that you’re working with right now?
One of the projects I work on is the Exoplanet Climate Infrared TELescope (EXCITE). EXCITE is a scientific balloon-borne telescope that is designed to measure the spectra of hot, Jupiter-like exoplanet atmospheres in near-infrared light.
What is your role for that?
I do a little bit of everything. During grad school, I worked on the first few iterations of the proposal for EXCITE back in 2015 and 2016.
Over the past few years here at Goddard, I’ve been responsible for parts of a lot of the different subsystems like the cryogenic receiver, the gondola, the electronics, and integration and testing of the whole payload.
Last year, we went to Fort Sumner, New Mexico, for an engineering flight. Unfortunately, we were not able to fly for weather reasons. We went back last month, and I was again part of the field deployment team. We take the whole instrument, break it down, carefully ship it all out to New Mexico, put it back together, test it, and get it ready for a flight.

What I like about working on a project like EXCITE is that we get to kind of do a little bit of everything.
We’ve been able to see the experiment from concept and design to actually getting built, tested and hopefully flown and then subsequent data analysis after the flight. What I think is really fun is being able be with an experiment for the entire life cycle.
How do you help support Goddard’s mission?
We’re studying exoplanets, which definitely fits within the scientific mission of Goddard. We’re also a collaboration between Goddard other academic institutions, like Arizona State, like Brown University, Cornell, and several other places, and so we’re also members of the larger scientific research community beyond NASA.
We also have a number of graduate students working on EXCITE. Ballooning is a good platform for training students and young researchers to learn how to build and design instruments, do data analysis, etc. One of the missions of NASA and Goddard is to train early career scientists like graduate students and post docs, and balloons provide a good platform for that as well.
Balloon missions like EXCITE also provide a good platform for technology advancement and demonstration in preparation for future satellite missions.
How did you know cosmology was what you wanted to pursue?
When I was a kid, I loved space. I wanted to be an astronaut when I was a kid. I even went to space camp.
The first time I ever got to see physics was a middle-school science class. That was the first time we ever learned physics or astronomy that was deeper than just identifying planets or constellations. We started to learn how we could use math to measure or predict experiments.
When I was in college, I remember talking to my undergraduate academic adviser, Glenn Starkman, and talking about what research I might like to do over the summer between sophomore and junior year of college. I wasn’t really sure what I wanted to do or what I was interested in, and he suggested I talk to some of the professors doing astrophysics and cosmology research and see if they had space for me in their lab.
I ended up finding a great opportunity working in a research lab in college — so it was working in the physics department in Case Western.
That’s where I first started learning about computer-aided design (CAD), and designing things in CAD, and that’s where I first learned how things get made in a machine shop, like on a mill, or a lathe. These skills have come in handy ever since, because I do a lot of design work in the lab. And I was lucky growing up that my dad was really hands-on and liked to fix things and build things and he taught me a lot of those skills as well.
Who has influenced you in your life?
My dad had a big influence. I think all the different people I’ve had the opportunity to learn from and work with who have been mentors along the way. My research advisers, professor John Ruhl in college, professor Greg Tucker in grad school, and Dr. Ed Wollack as a postdoc have all been very influential. Additionally, I have had the opportunity to work with a lot of very good post docs and research scientists during my career, Dr. Asad Aboobaker, Dr. Britt Reichborn-Kjennerud, Dr. Michele Limon, among others.
Throughout a career, there are tons of other people on the way from whom you pick up little things here and there that stick with you. You look back and you realize five years later you still do this one thing a certain way because someone helped you and taught you this skill or technique.
Where is a place you’d like to travel to?
Since I was lucky enough to go to Antarctica in graduate school, I figured that is the hardest continent to travel to, so now I have a mission to go to every continent. I’ve been to North America, I’ve been to South America, I’ve been to Asia, Europe, and Australia and New Zealand, but I’ve never been to Africa.
Kyle Helson (second from left) races the keirin at the Valley Preferred Cycling Center in Breinigsville, PA. Photo Credit Dr. Vishrut GargWhat are your hobbies, or what do you enjoy doing?
I’m a competitive track cyclist. I started racing bikes in collegiate racing as a grad student at Brown. Many summers I’ve spent many weekends driving and flying all over the U.S. to race in the biggest track cycling events in the country.
What would be your three-word-memoir?
Curious, compassionate, cat-dad.

Sols 4297-4299: This Way to Tungsten Hills This image was taken by Left Navigation Camera aboard NASA’s Mars rover Curiosity on Sol 4296 — Martian day 4,296 of the Mars Science Laboratory mission — on Sept. 6, 2024, at 06:47:03 UTC. NASA/JPL-CaltechEarth planning date: Friday, Sept. 6, 2024
Contact science in our immediate workspace includes a joint effort by MAHLI and APXS to characterize a gray rock with two targets named “Big Baldy” and “Big Bird Lake.” ChemCam focused its Laser Induced Breakdown Spectroscopy (LIBS) instrument on a rock with a reddish coating, “Purple Creek,” and a light-toned rock, “Garlic Meadow,” to determine their chemical composition. ChemCam included a long distance RMI image of the yardang unit that caps Mount Sharp as well as a standard post-drive AEGIS activity, which allows autonomous target selection for upcoming geochemical spectrometry.
The Mastcam team assembled several beautiful mosaics to document Curiosity’s surroundings. One mosaic will extend the imaging of the current workspace and is planned at dusk to take advantage of the diffuse lighting. Two separate mosaics, one of which is in stereo, will characterize the floor of the depression in front of Tungsten Hills to investigate the exposed light rocks and document depositional processes. Finally, a stereo mosaic will image Tungsten Hills and the surrounding terrain in advance of our approach over the weekend.
With the weekend plan in place the science team will now patiently wait for data to be returned and for planning to resume on Monday!
Curiosity completed an impressive 60-meter drive (about 197 feet) across the channel floor within Gediz Vallis and parked along the edge of a shallow linear depression. Just about 20 meters (66 feet) away, an intriguing dark, textured rock named “Tungsten Hills” is the destination for our weekend drive and our contact science on Monday. Today I served as the “Keeper of the Plan” for the Geology theme group and worked with the science team to compile a variety of contact science and targeted science in this three-sol plan.

NASA JPL Scientists, Engineers Collaborate With Artists for Exhibition
5 min read
Preparations for Next Moonwalk Simulations Underway (and Underwater) Artist David Bowen works on “tele-present wind,” featuring grass stalks that move in response to Martian wind data previously collected by NASA’s Perseverance rover mission. Behind him sits JPL data systems architect Rishi Verma.NASA/JPL-CaltechWorks in ‘Blended Worlds: Experiments in Interplanetary Imagination,’ an exhibit in Glendale, California, help shrink the universe into something tangible.
The universe is vast and filled with countless worlds, but a new exhibit at the Brand Library & Art Center in Glendale, California, aims to shrink time and space. For “Blended Worlds: Experiments in Interplanetary Imagination,” artists collaborated with scientists and engineers from NASA’s Jet Propulsion Laboratory to create cross-disciplinary works that help illuminate the universe by bringing art and science together.
On view from Sept. 21, 2024, to Jan. 4, 2025, the exhibition is part of “PST ART: Art & Science Collide,” an event presented by the Getty and involving more than 70 exhibitions from museums and institutions across Southern California exploring the intersection of art and science.
“The magic of art is that it enhances our experiences and interactions with the world — and in this case, our universe,” said Dr. Laurie Leshin, director of JPL in Southern California. “We’re honored to work with great artists to bring the wonders of space to our community through this exhibition, which invites us all to be part of a grand journey of exploration and discovery.”
The 126 grass stalks of “tele-present wind” are attached to mechanical tilting devices that move in response to Martian wind data.NASA/JPL-CaltechDavid Bowen’s installation “tele-present wind” features grass stalks attached to tilting mechanical devices that move in response to Martian wind data previously collected by NASA’s Perseverance rover mission. Helping make the effort possible were Rishi Verma, a data systems architect at JPL, and José Antonio Rodríguez-Manfredi, the principal investigator of the Mars Environmental Dynamics Analyzer (MEDA) system on Perseverance.
For “Seismic Percussion,” artist Moon Ribas creates an interplanetary drum score by translating seismic data from Earth, the Moon, and Mars. For Mars data, JPL’s Verma worked with Nobuaki Fuji of the Institut de Physique du Globe de Paris, who collaborated on NASA’s now-retired InSight lander. Ceri Nunn, a JPL planetary scientist, assisted with moonquake data.
Also featured is a handwritten version of U.S. Poet Laureate Ada Limón’s “In Praise of Mystery: A Poem for Europa,” the poem she dedicated to NASA’s Europa Clipper mission, which is targeting an October launch and will make multiple flybys of Jupiter’s icy moon Europa. The poem has been etched onto a metal plate on the spacecraft and will ride with the orbiter on its long journey.
Additional works allow visitors to experience Earth’s wonders through scents, use sound to convey the vast distances between our planet and those beyond our solar system, and blend heartbeats and other Earthly sounds with sonified data from Europa’s magnetic field.
“We were looking to create imaginative opportunities for people to connect with each other as they connect with the awe-inspiring science being conducted today,” said David Delgado, a cultural strategist and the project lead at JPL. “I know this experience has really opened the eyes of everyone collaborating on the project, and we hope it does the same for people who come to see ‘Blended Worlds.’”
As part of PST ART, a number of public programs and community events will also accompany the “Blended Worlds” gallery exhibition, including “Blended Worlds: An Evening of Art, Theater, and Science” hosted by Reggie Watts at the Alex Theatre in Glendale on Oct. 5, and “Earth Data: The Musical,” an original musical developed by Theater Arts at Caltech exploring the challenges of climate research and science as a human pursuit at Caltech’s Ramo Auditorium Nov. 1 to 3.
Artists’ collaborations with JPL and the display of their works at Glendale’s Brand Library were made possible by the generous support of the Glendale Arts and Culture Commission and the Glendale Library, Arts & Culture Trust.

“It’s 2 a.m. in the morning on a Sunday. You have your headset in your hand. You’re about to walk into Mission Control. And you understand — in the darkness, the crickets chirping, the lights shining on the building — you understand where you’re going and what you’re a part of.
“This is the building where we heard astronauts say, ‘Houston, we’ve had a problem.’ Where we heard, ‘the Eagle has landed.’ And the people on the ground supporting those historic missions were in this building — and now I get to be a part of that.
“There is just this undying sense of wonder every time I walk into this building. Not to say that there isn’t an undying sense of wonder at many of the other buildings at Johnson [Space Center]. But with this building in particular, having that ownership and that responsibility as I walk in — that will never go away. It’s wonderful.”

Find Me on the Moon: NASA Lunar Navigation Challenge
NASA’s Artemis campaign is a series of lunar missions to further explore the lunar landscape to prepare for future missions to Mars. The Artemis missions will send humans to land on the moon and explore the lunar south pole. This will be NASA’s first human lunar landing since the Apollo missions over 50 years ago. The Artemis missions will be landing at the lunar south pole; this area is of interest because the permanently shadowed regions that exist there may be traps for water ice which could be accessed to support future missions to Mars. One area of interest is Shackleton Crater, measuring 13 miles (21 km) in diameter and 2.6 miles (4.2 km) deep. The crater has steep sides and continuous shadows cause the floor of the crater to be below 90 K and may have water ice trapped beneath the surface. To support these missions, NASA is seeking two solutions: one low-tech and one high-tech. While both solutions are related to navigation, they are independent challenges and solutions.
For Challenge 1, NASA is seeking an orienteering aid that will help the astronauts navigate on traverses away from the lunar lander and return back. While there were similar devices available to the Apollo astronauts, NASA is looking for new and unique solutions. Among other considerations, devices must be accurate, easy to use, able to be used on the moon’s surface by an astronaut wearing pressurized gloves. If your solution is one of the best, you could be eligible for a share of the $15,000 prize purse.
For Challenge 2, NASA is looking for assistance in getting to and mapping the bottom of Shackleton Crater. The design must work in the extreme conditions of the lunar south pole and Shackleton Crater, map the crater, characterize and quantify what is in the crater, and send the data back to be used for future missions. If you can solve this challenge by describing your design concept in detail, you could be eligible for a share of the $30,000 prize purse.
In addition, there is $5,000 in prize money to be distributed among solutions from both challenges that show exceptional achievement.
Award: $50,000 in total prizes

NASA’s Hubble, Chandra Find Supermassive Black Hole Duo This is an artist’s depiction of a pair of active black holes at the heart of two merging galaxies. They are both surrounded by an accretion disk of hot gas. Some of the material is ejected along the spin axis of each black hole. Confined by powerful magnetic fields, the jets blaze across space at nearly the speed of light as devastating beams of energy. NASA, ESA, Joseph Olmsted (STScI)Download this artist’s depiction
Like two Sumo wrestlers squaring off, the closest confirmed pair of supermassive black holes have been observed in tight proximity. These are located approximately 300 light-years apart and were detected using NASA’s Hubble Space Telescope and the Chandra X-ray Observatory. These black holes, buried deep within a pair of colliding galaxies, are fueled by infalling gas and dust, causing them to shine brightly as active galactic nuclei (AGN).
This AGN pair is the closest one detected in the local universe using multiwavelength (visible and X-ray light) observations. While several dozen “dual” black holes have been found before, their separations are typically much greater than what was discovered in the gas-rich galaxy MCG-03-34-64. Astronomers using radio telescopes have observed one pair of binary black holes in even closer proximity than in MCG-03-34-64, but without confirmation in other wavelengths.
AGN binaries like this were likely more common in the early universe when galaxy mergers were more frequent. This discovery provides a unique close-up look at a nearby example, located about 800 million light-years away.
A Hubble Space Telescope visible-light image of the galaxy MCG-03-34-064. Hubble’s sharp view reveals three distinct bright spots embedded in a white ellipse at the galaxy’s center (expanded in an inset image at upper right). Two of these bright spots are the source of strong X-ray emission, a telltale sign that they are supermassive black holes. The black holes shine brightly because they are converting infalling matter into energy, and blaze across space as active galactic nuclei. Their separation is about 300 light-years. The third spot is a blob of bright gas. The blue streak pointing to the 5 o’clock position may be a jet fired from one of the black holes. The black hole pair is a result of a merger between two galaxies that will eventually collide. NASA, ESA, Anna Trindade Falcão (CfA); Image Processing: Joseph DePasquale (STScI)Download this image
The discovery was serendipitous. Hubble’s high-resolution imaging revealed three optical diffraction spikes nested inside the host galaxy, indicating a large concentration of glowing oxygen gas within a very small area. “We were not expecting to see something like this,” said Anna Trindade Falcão of the Center for Astrophysics | Harvard & Smithsonian in Cambridge, Massachusetts, lead author of the paper published today in The Astrophysical Journal. “This view is not a common occurrence in the nearby universe, and told us there’s something else going on inside the galaxy.”
Diffraction spikes are imaging artifacts caused when light from a very small region in space bends around the mirror inside telescopes.
Falcão’s team then examined the same galaxy in X-rays light using the Chandra observatory to drill into what’s going on. “When we looked at MCG-03-34-64 in the X-ray band, we saw two separated, powerful sources of high-energy emission coincident with the bright optical points of light seen with Hubble. We put these pieces together and concluded that we were likely looking at two closely spaced supermassive black holes,” said Falcão.
In a surprise finding, astronomers, using NASA’s Hubble Space Telescope have discovered that the jet from a supermassive black hole at the core of M87, a huge galaxy 54 million light years away, seems to cause stars to erupt along its trajectory. The stars, called novae, are not caught inside the jet, but in a dangerous area near it.NASA’s Goddard Space Flight Center; Lead Producer: Paul Morris
To support their interpretation, the researchers used archival radio data from the Karl G. Jansky Very Large Array near Socorro, New Mexico. The energetic black hole duo also emits powerful radio waves. “When you see bright light in optical, X-rays, and radio wavelengths, a lot of things can be ruled out, leaving the conclusion these can only be explained as close black holes. When you put all the pieces together it gives you the picture of the AGN duo,” said Falcão.
The third source of bright light seen by Hubble is of unknown origin, and more data is needed to understand it. That might be gas that is shocked by energy from a jet of ultra high-speed plasma fired from one of the black holes, like a stream of water from a garden hose blasting into a pile of sand.
“We wouldn’t be able to see all of these intricacies without Hubble’s amazing resolution,” said Falcão.
The two supermassive black holes were once at the core of their respective host galaxies. A merger between the galaxies brought the black holes into close proximity. They will continue to spiral closer together until they eventually merge — in perhaps 100 million years — rattling the fabric of space and time as gravitational waves.
The National Science Foundation’s Laser Interferometer Gravitational-Wave Observatory (LIGO) has detected gravitational waves from dozens of mergers between stellar-mass black holes. But the longer wavelengths resulting from a supermassive black hole merger are beyond LIGO’s capabilities. The next-generation gravitational wave detector, called the LISA (Laser Interferometer Space Antenna) mission, will consist of three detectors in space, separated by millions of miles, to capture these longer wavelength gravitational waves from deep space. ESA (European Space Agency) is leading this mission, partnering with NASA and other participating institutions, with a planned launch in the mid-2030s.
NASA’s Marshall Space Flight Center manages the Chandra program. The Smithsonian Astrophysical Observatory’s Chandra X-ray Center controls science from Cambridge, Massachusetts and flight operations from Burlington, Massachusetts. Northrop Grumman Space Technologies in Redondo Beach, California was the prime contractor for the spacecraft.
The Hubble Space Telescope has been operating for over three decades and continues to make ground-breaking discoveries that shape our fundamental understanding of the universe. Hubble is a project of international cooperation between NASA and ESA (European Space Agency). NASA’s Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope and mission operations. Lockheed Martin Space, based in Denver, Colorado, also supports mission operations at Goddard. The Space Telescope Science Institute in Baltimore, Maryland, which is operated by the Association of Universities for Research in Astronomy, conducts Hubble science operations for NASA.

NASA, Boeing Welcome Starliner Spacecraft to Earth, Close Mission
NASA and Boeing safely returned the uncrewed Starliner spacecraft following its landing at 10:01 p.m. MDT Sept. 6 at White Sands Space Harbor in New Mexico, concluding a three-month flight test to the International Space Station.
“I am extremely proud of the work our collective team put into this entire flight test, and we are pleased to see Starliner’s safe return,” said Ken Bowersox, associate administrator, Space Operations Mission Directorate at NASA Headquarters in Washington. “Even though it was necessary to return the spacecraft uncrewed, NASA and Boeing learned an incredible amount about Starliner in the most extreme environment possible. NASA looks forward to our continued work with the Boeing team to proceed toward certification of Starliner for crew rotation missions to the space station.”
The flight on June 5 was the first time astronauts launched aboard the Starliner. It was the third orbital flight of the spacecraft, and its second return from the orbiting laboratory. Starliner now will ship to NASA’s Kennedy Space Center in Florida for inspection and processing.
NASA’s Commercial Crew Program requires a spacecraft to fly a crewed test flight to prove the system is ready for regular flights to and from the orbiting laboratory. Following Starliner’s return, the agency will review all mission-related data.
“We are excited to have Starliner home safely. This was an important test flight for NASA in setting us up for future missions on the Starliner system,” said Steve Stich, manager of NASA’s Commercial Crew Program. “There was a lot of valuable learning that will enable our long-term success. I want to commend the entire team for their hard work and dedication over the past three months.”
NASA astronauts Butch Wilmore and Suni Williams launched on June 5 aboard Starliner for the agency’s Boeing Crewed Flight Test from Cape Canaveral Space Force Station in Florida. On June 6, as Starliner approached the space station, NASA and Boeing identified helium leaks and experienced issues with the spacecraft’s reaction control thrusters. Following weeks of in-space and ground testing, technical interchange meetings, and agency reviews, NASA made the decision to prioritize safety and return Starliner without its crew. Wilmore and Williams will continue their work aboard station as part of the Expedition 71/72 crew, returning in February 2025 with the agency’s SpaceX Crew-9 mission.
The crew flight test is part of NASA’s Commercial Crew Program. The goal of NASA’s Commercial Crew Program is safe, reliable, and cost-effective transportation to and from the International Space Station and low Earth orbit. This already is providing additional research time and has increased the opportunity for discovery aboard humanity’s microgravity testbed, including helping NASA prepare for human exploration of the Moon and Mars.
